LUMBER GRADING

WHAT IS LUMBER GRADING?

When lumber is used as a structural material in construction, it has to perform properly. It must be strong enough, stiff enough, dry enough, etc; to meet the required performance levels.

In Canada, a sophisticated system of product standards, engineering design guidelines, government regulations, education, reviews, and check and balances has evolved over the years to help people determine what lumber they need for a specific building project, and what grade of lumber they are receiving.

Since 1960, virtually all of the lumber produced in Canada has been marked with a nationally standardized, easy-to-read Lumber Grade Stamp placed right on the wood itself. These stamps identify the species, grade and moisture content of the piece of lumber, its facility of origin, the logo of the accredited Grading Agency that has overseen its grading, and any special processing the lumber has received.

Grade stamps and certificates are the basis of sale, purchase, and regulatory acceptance of the lumber manufactured in Canada.

HOW TO READ A LUMBER GRADING STAMP

  • Accredited Grading Agency logo certification trademark

    This trademark certifies the legitimacy and accredidation of the wood product.

  • Lumber Grade

    Common grades of visually graded lumber include: SEL STR (Select Structural)

    No. 1, No. 2

    No. 3 / Stud / Stand & Btr. (or Standard & Better)

    (May just have the grade number alone)

  • Phytosanitary Treatment

    These may include:

    HT (Heat Treated to the international standards for core temperature and length of time sufficient to kill a series of pests.

    (This is often combined Kiln Drying of lumber, to produce a stamp reading KD-HT).

    (May just have the grade number alone)

  • Facility Identification

    Firm name, brand, or mill number. This allows lumber to be traced back to the place of origin.

  • Seasoning or Moisture Content

    Common grades of visually graded lumber include: SEL STR (Select Structural)

    Mc – (number) (Percentage moisture content. MC-15, for example, means the lumber had a maximum moisture content of 15% when it was produced).

    KD (Kiln Dried to a maximum moisture content of 19%. This may also include a lesser moisture content number such as KD-15).

    S-Dry (19% maximum moisture content at time of surfacing).

    S-GRN (more than 19% maximum moisture content, or unseasoned).

    (May just have the grade number alone)

  • Grade Rule

    When lumber is graded to the National Lumber Grading Authority rules, the stamp will include NLGA.

    Wood Species or Species Combination

    Common designation are:

    S-P-F (or Spruce – Pine – Fir)

    Hem-Fir (N) (or Hemlock – Fir)

    D. Fir-L (N) ( or Douglas Fir – Larch)

    N. Species (include red cedar, certain pines, balsam and poplars)

    Note: The Canadian and U.S. versions may have a different mix of species, with different structural rating. The U.S. species groups are identified with an “S”, and the Canadian with an ”N”.

OVERVIEW

FORESTRY

Ontario has four main forest cover types:

Deciduous forest – mostly north of Lake Erie – witch adds many species commonly found in the states of Ohio, Pennsylvania and the Carolinas.

Great Lakes – St. Lawrence forest – the second largest forest region – with a wide range of coniferous and deciduous tree and shrub species.

Boreal forest – the largest forest region in Ontario, which consists predominantly of black and white spruce, jack pine, balsam fir, tamarack and eastern white cedar, as well as poplars and white birch.

Hudson Bay Lowlands – subarctic barrens with black and white spruce and willow trees.

The forests fill many roles (see link Environment and Markets). They are valuable resource and deserve careful management. “Careful management” doesn’t mean just leaving all the forests in their current state, though. It means undertaking detailed planning studies, including those required under Ontario’s Crown Forest Sustainability Act, and then following the resulting recommendations for proactive silviculture, protected areas, operations and management.

Silviculture is the art and science used to grow healthy trees in stands, forests and landscapes. It is built on Knowledge of how forests have been shaped by the environment over the thousands of years, in both nurturing and destructive ways. It examines the natural cycles of growth, aging add rebirth of forests, the influence of climate, pests, and fire, and the impacts of different methods of harvesting and management.

Modern forest management combines the best silviculture practices to protect trees from many threats, to maintain diverse uses, respect ecological concerns such as biodiversity, wildlife habitat and water quality, and to allow access to and harvesting of trees for a variety of wood products.

To today’s foresters, who study the constant cycles in the forest ecosystem, appropriate harvesting of trees with a properly managed forest is not the end of the forest, but an important part of its renewal.

ENVIRONMENT

Canada’s Forests are an important environmental resource, contributing to water quality, air quality, soil stability, wildlife habitat, and biodiversity. They also are affected by - and they affect - climate change.

The Province of Ontario contains more than 70 million hectares of forested land. Ninety percent of this area is owned by the provincial government: It is referred to as ‘Crown forest’. About 26 million hectares of this Crown forest is managed for a broad range of uses and benefits.

Ensuring the long-term health of forest ecosystems is the primary objective of forest management on Crown land in Ontario. Through the Ministry of Natural Resource’s forest management planning process, forest managers ensure that the forests of Ontario will remain healthy in the future to provide sustainable benefits such as timber and commercial products, wildlife habitat, and recreation opportunities for the people of Ontario, as well as global environmental benefits.

Ontario was the first province in Canada to subject its forest management planning process to a comprehensive, in-depth Environmental Assessment. Board hearings covered concerns raised by aboriginal peoples, forest interest groups and the public. Its decision in 1994 approved the planning process, but added new conditions for impacts on non-timber resources, managing for water, wildlife, aesthetic and cultural values, and involvement of local communities. This place Ontario forest managers at the leading edge of sustainable forest management. An updated environment approval in 2003 has continued this evolution.

Management of Crown forests in Ontario is the responsibility of the provincial government, but this responsibility is shared with forest products companies and communities. There is a significant role for the citizens of Ontario, including local communities, first nations and environmental groups, to participate in the planning process. Their involvement helps to balance the social, economic and environmental objectives of the management of the Crown forest. Monitoring programs keep tabs on compliance with the forest management plans, effectiveness of silviculture renewal, and forest health.

Independent forest audits also provide a third-party assessment of compliance with legal requirement, comparison of planned versus actual forest management activities, identification of how well activities are achieving audit criteria and management objectives and, where applicable, assessment of the licensee’s compliance with the terms and conditions of a sustainable forest license.
